Project Scope

The Contractor shall provide labor, materials, equipment and supervision to perform the following work:

The contractor shall remove and discard the existing water evaporator sections of 6 make-up air handling units (MAUs) - Numbers 15,16,18,20,21,and 22 from attached drawing. The contractor shall remove all obsolete controls that will no longer be used with the new section. The contractor shall install a new direct evaporative cooling section that is compatible and functional with the existing units.

Provide bid options for Numbers 19,25,26,27, and 28 in the case that additional funding becomes available.

The new evaporative sections shall meet the following minimum characteristics:

The section frame shall come equipped with welded eyelets for hoisting the unit in place. Eyelets shall be sized to lift the full weight of the sections.

The casing of the evaporative section shall consist of 16 gauge, stainless steel cabinetry and supports.

All seams are to be welded. All nuts, bolts, washers, screws, rivets or other fasteners shall be stainless steel.

The sump tank shall be made of 14 gauge stainless steel.

The bottom of the sump shall be constructed with a cross break for proper drainage of the sump.

Once unit is set, the supply water (1/2”, ¾”, or 1” copper slip std.) drain and overflow (3/4”, 1”, 1 ½”, or 2” MPT std.), plumbing connections may be made.

A PVC Sch. 40 MPT plug shall be provided at the interior side of the drain connection on standard units.

Automatic sump drain valves shall be installed using a full open N/C solenoid valve. The JCI Metasys shall provide on/off control. The contractor shall provide and install these valves and the control work necessary to be programmed from the Building automated system (BAS).

The sump drain shall be plumbed per the international plumbing code

The water distribution systems shall be constructed of copper pipe, sized for adequate water distribution. A copper spray manifold shall be assembled to create 3 horizontal stages equal to the proportion of the cooling media. Initial staging shall start first initializing the full open solenoid valve of the middle section spray bank.

A balancing type valve shall be installed on the discharge side of the spray pump so that the spray pattern may be regulated.

Non-clogging brass inset nozzles shall be used to eliminate water corrosion and scaling. The spray nozzles design will spray directly on to the face of the media as opposed to a drip system.

A brass submersible energy efficient distribution pump shall have characteristics to sustain the environment and be able to maintain its integrity for an above average life cycle without rusting or corroding. The pump shall be 120v. A stainless steel pump screen assembly shall be supplied to prevent clogging.

Quick-coupling fittings and wiring disconnect shall be installed to facilitate the removal of the spray pump.

The float valve shall be cast brass with 1” water inlet line and attached with a brass ball float.

Side discharge overflow outlet shall be installed in the side housing of water basin.

A bug screen shall be installed on the nipple outlet and an end cap shall be provided for capping it in the off season.

Media: The evaporative media shall be eighteen inches (18”) thick (GLASdek/Tuff Edge type media). It is specially engineered, flame retardant material, making it the media choice where strict adherence to fire codes is required – Fire Rated UL®900, Class II.

DAMPERS:

Outside air damper section shall be a formed adjustable louver with drainable blades Frame: 4” x 20 ga. galvanized steel Blades: 20 ga. galvanized steel Blade Angle: 45◦ Axeles: ½” dia. plate steel Linkage: Plated steel concealed on jamb Operator: Electronic actuators operating in response to a 4 to 20 mA control input and or 2 to 10 VDC feedback signal.

Intake louver shall be equipped with bird screen.

Screen: bird screen – ½”x ½” x 19ga. galvanized steel All electrical work shall be run within the interior of the MAU

Evaporative Control Sequence:

The controls for this new section shall be incorporated into and compatible with the existing Johnson Control Metasys building automation system. The control programming shall operate as follows:

Normal - on start up, the dampers are opened to 10% minimum position (modulating). The supply fan variable drive is controlled by the desired/adjustable duct static pressure. The damper sections will modulate based on the mode (H/C) parameters and duct static pressure.

Cooling Mode:

I.e. when the outside air is greater than 65 degf. (adjustable set point) the dampers will open to 100% Cooling is initiated by the discharge air temperature set point (DASPT), outside air temperature shall be used as the first stage of cooling.

When outside air temperature is greater than the DASPT, the 1st stage of evaporative cooling is initialized and the bottom solenoid valve is energized to the first zone spray manifold. If the set point is not reached (20 min. adjustable) the next zone up shall be energized, typical for the remaining spray zones.

When the desired DASPT is reached spray solenoid(s) are de-energized in sequence.

Humidity control shall be provided by a humidistat located in the occupied space providing the best reference. Once a high limit humidity setpoint has been obtained, a de-energizing sequence (described above) shall begin. A control program lock out of the spray distribution shall be held until the space humidity is 5% less than the RH limit adjustable set point.

A reference temperature sensor (if not existing) shall be installed in the room best referenced by the MAU.

Heating Mode:

I.e. when outside air temperature is less than 45 degrees F. the dampers will go to the10 % minimum open position while maintaining desired static duct pressure.

When the outside air temperature is less than 65 degrees F., the MAU hot water reticulating pump shall turn on and the heating valve modulates to satisfy discharge air set point.

The heating valve shall be programmed to maintain a constant 10% flow through the heating coil at 45 degrees outside air and below.

All controls for the new evaporative cooling units shall be compatible and operable using the existing Johnson Controls Metasys building automation system. A system graphic shall be created for each MAU system.

The filter and operable damper sections shall be constructed of galvanized metal.

The damper section shall be supplied with a galvanized steel bird screen in a removable frame on the interior of the louver.

Environmental Procedures

90-Day Storage Area: Emergency Hazardous Waste Spill Response

Note: This procedure needs to be included for demolition projects, for the potential exists that hazardous materials may have been unknowingly used during the original construction and may be discovered during demolition operations (e.g., asbestos in old dry walls, PCBs in electrical ballasts, lead or other heavy metals in old painted surfaces).

1.0 Purpose

The purpose of this procedure is to provide emergency response for spills of hazardous materials in the two 90-day storage areas (Building 47 and 11) and designated satellite accumulation areas

Sections: 2.0 Activity/Department, 3.0 Forms Used, 4.0 References, 5.0 Acronyms, and

6.0 Exclusions, are not included, for all information is found in the Procedure Section.

7.0 Procedure

A copy of the spill response plan is found in the 90-day storage areas at the following locations: Building No. 11 in the door pouch on the outside of each room, Building No.

47 in a marked yellow overpack drum located in the northeast corner of the enclosure.

7.1 Individuals Without Spill Response Training

An individual without spill response training observes a spill shall immediately:

Evacuate the area of all personnel that could potentially be impacted

Call the Mega Center at 303-236-2911 and report the spill

Call the DFC Environmental Program Manager, Mr. John Kleinschmidt at 303-236-8000 x 5030 or Mr. Michael Gasser at 303- 236-8000 x 5057

Stay clear of the area until trained personnel arrive – West Metro Fire is the DFC Hazardous Material Emergency Response Team

7.2 Individuals Trained To Respond To Minor Spills

These are spills which the person has been trained and is comfortable in handling. The individual should only attempt to clean up this spill if they have been trained to do this work and have knowledge in how to appropriately handle the chemicals involved. Under no circumstance should personnel attempt to clean up the spill if they are not trained to respond. These generally are in quantities less than 2-3 gallons or 10 pounds. The individual should:

Put on personal protection equipment if required

Secure the area to prevent others from being exposed

Initiate clean up

Protect further spread of chemicals

Notify appropriate management

Notify Mr. Kleinschmidt with the EPG at 303-236-8000 x 5030

Appropriately containerize cleaned up waste, appropriately label, and store in Building 11, a designated 90-day storage area.

7.3 Major Spills or Spills Involving Highly Hazardous Materials

All trained and untrained personnel should respond similarly to untrained minor spill observer (Section 7.1)

They shall:

Evacuate the area of all personnel that could potentially be impacted

Call the Mega Center at 303-236-2911 and report the spill

Call the DFC Environmental Program Manager, Mr. John Kleinschmidt at 303-236-8000 x 5030 or Mr. Michael Gasser at 303-236-8000 x 5057

Stay clear of the area until trained personnel arrive – West Metro Fire is the DFC Hazardous Material Emergency Response Team

7.3.1 Emergency Response Procedures

IMMEDIATELY UPON DISCOVERY OF AN IMMINENT OR

ACTUAL EMERGENCY, THE WMD/HazMat COORDINATOR WILL

BE CONTACTED WHO WILL:

Notify facility personnel. Summons the West Metro Fire Department and Jefferson County Hazmat Team 9-911. Account for all personnel. Determine if there are any injuries.

Notify emergency response and reporting agencies listed in section

7.5, as necessary.

Identify the character, exact source, amount and extent of any released material. If the spilled material is flammable, turn off ignition and heat sources but not lights or electrical equipment, then call the fire department. Attend to any person who needs medical assistance or who may have been contaminated. Evacuate the facility in accordance with the GSA Occupant Emergency Plan.

Federal Protective Services will be responsible for update and implementation of the plan.

Assess hazards to the environment and human health, including direct and indirect effects from fires, explosions, and spills (e.g., toxic, irritating, asphyxiating vapors or gases, surplus water runoff, etc.)

DURING THE EMERGENCY CONTROL PHASE, THE EMERGENCY

COORDINATOR MUST:

Take measures to ensure the incident does not recur or spread to other hazardous material areas at the facility. Shut down operations and evacuate building if necessary.

Criteria for facility evacuation:

Small quantity release: Release with low potential of spreading beyond the Building 11 room or beyond a 20 foot radius from the source of the release at Building No. 47 West Fenced Storage Area where it occurred: evacuate personnel in the room or the storage area.

Medium quantity release: Release with potential of spreading to adjacent rooms in Building 11 or beyond a 20 foot radius from the source of the release at Building No. 47 West Fenced Storage Area:

evacuate personnel in the room where the release occurred and the adjacent rooms in the building, for releases in the fenced storage area, any personnel in Building No. 47 will be evacuated.

How facility personnel will be evacuated: Personnel will walk unless disabled, in which case they will be assisted by other personnel evacuating facility.

It is important to note that Building 11, rooms 2, 3, 6 and 7, and

Building No. 47 West Fenced Storage Area are not an occupied building/area and any personnel entering will have appropriate

RCRA and OSHA training to enter a Large Quantity Generator 90-day hazardous waste storage area.

The control of the spread of a release of hazardous materials or contaminants will be coordinated by the response team commander.

The GSA Buildings Manager will coordinate any necessary utilities shutdown. The location of sewers, damming/booming locations, utilities shutoffs, etc will be provided by GSA personnel to the

Emergency Coordinator or designated response team/incident commander, as necessary.

7.4 Evacuation Plan

All evacuations should be done upwind. Evacuation is the standard procedure for all types of hazardous materials incidents. The facility evacuation plan is contained in GSA’s Occupant Emergency Plan.

Situations which would warrant partial or complete evacuation of the area are as follows:

Explosions resulting in airborne debris including container fragments and hazardous wastes. Minimum safe distance from flying fragments is 2,000 feet.

Spills or Chemical Reactions resulting in highly toxic fumes. Evacuate personnel based on above criteria. Possible evacuation of persons working or living downwind of the facility may be necessary.

Fire when it cannot be contained and is spreading to other parts of the facility or when it could generate toxic fumes.

Evacuate Immediate Area:

If potential exists for heat-induced explosions, evacuate area to a safe distance (at least 2,000 feet) in all directions from the fire.

Routes:

Occupants exit building through the nearest exit as per building evacuation plan and meet at designated meeting area.

Before operations are resumed in the affected areas, the WMD/HazMat

Coordinator, the GSA Industrial Hygienist, and emergency response personnel will assess the situation and conditions to determine when it is safe to re-enter the building.

Asbestos Management

Note: Contractors and staff need to be aware of the Asbestos Awareness statement. For contractors responsible for the removal of asbestos Section 7.5 is relevant.

GSA strives to acquire and manage space free of asbestos-containing material (ACM).

It is GSA’s policy to minimize asbestos exposure to all building occupants and is building specific to address the types, quantity, and location of ACM. GSA minimizes asbestos exposures by all building occupants through managing asbestos in place.

Asbestos Awareness Statement

GSA is making its staff and contractors aware of asbestos for GSA buildings are generally older in construction and built when asbestos was commonly used.

Asbestos is a naturally occurring substance and was used in about 3000 different building materials. For years construction materials used asbestos to improve its strength or elasticity properties, and to make materials resistant to chemicals and heat.

GSA conducts asbestos inspections in-house every year and hire a certified building inspector every five years to assess conditions of known areas. The approved GSA method of handling asbestos is called “managing in place”. When possible known or suspected material has been tested and labeled accordantly with “Non-Asbestos Material” or “Danger - Asbestos Containing Material”. This material posses no threat in the condition it is in. Only when it is absolutely necessary to be removed, will it then be removed. If you see friable material;

crumbly, easily broken into small fragments or reduced to powder contact the

Building Manager.

Do not touch asbestos materials, contact the Building Manager. People contracted to work with asbestos shall be properly trained and certified by the State of

Colorado in asbestos handling.

7.1 Buildings will receive an initial assessment to determine if ACM is present, its condition, location, and amount. A state-certified asbestos inspector shall conduct a “re-inspection” at a minimum of every five years. Buildings constructed after 1980 shall be assessed if no documentation can be provided that no ACM materials were used in the construction of the building.

7.1.1 Asbestos assessments shall be accomplished following the currently recognized standard protocol developed for schools under

Asbestos Hazard Emergency Response Act (AHERA) as promulgated in Title 40 CFR, Part 763 and as amended in the

Federal Register.

7.1.2 Sample locations shall be chosen in a non-random fashion, with emphasis on obtaining samples of each type of accessible, suspect material and minimizing damage to the material being sampled. All sampling shall be performed by State of Colorado licensed and certified inspectors.

7.1.3 Air monitoring shall be performed by state- licensed and certified air monitoring specialist. The Denver Federal Center Service Center

Asbestos Program Coordinator (DFCSCAPC) shall require that all air monitoring reports received be accompanied by air monitoring equipment calibration documentation.

7.2 Buildings with damaged ACM will be prioritized for repair or abatement by the DFCSCAPC.

7.3 Following the procedures detailed in the Rocky Mountain Region Form

Annual ACM Assessment (see section 8.0 Records), GSA management/ maintenance personnel shall be trained to complete the annual ACM inspection procedure.

7.4 All procedures will be developed, implemented, and monitored by the

DFCSCAPC and shall be reviewed by the Regional Asbestos Coordinator

(RAC).

7.5 All repair or abatement procedures will be conducted as per all applicable codes, standards, and regulations. The DFCSCAPC, with coordination with the RAC, shall review and approve all DFC repair or abatement procedures prior to commencing work. The DFCSCAPC shall ensure a State of

Colorado licensed and certified Asbestos Inspector serves as the non-affiliated third party monitor for all abatement procedures. The DFCSCAPC shall ensure all sample and air monitoring results are accompanied with sampling equipment calibration data.

Boiler Emissions

The purpose of the GSA Boiler Emissions Program is to optimize boiler operation to reduce air pollution. The program will ensure compliance with Federal, State, local and

GSA requirements.

7.1 Review state-specific requirements for boiler registration. For example, in

Colorado, new boilers with a capacity greater than 10 MM BTU must be registered by submitting an Air Pollution Emissions Notice.

7.2 Contractor schedules or performs flue gas analysis of boilers per contract guidelines.

7.3 Contractor coordinates annual state boiler inspections per contract guideline

7.4 Specifications in the Preventative Maintenance guides are used to determine performance & frequencies.

7.5 Reports are to be kept with the team managing the building as a permanent record after each test.

7.6 COR, will receive a copy of boiler inspections, flue gas analysis reports, and any discrepancies or problems and will submit a work order to the help desk for tracking and corrective action.

7.7 COR, will review reports and make recommendations as needed.

7.8 Review state requirements for boiler registration based on actual emissions.

Building Design & Specifications- Energy Use

To ensure all new and remodel construction projects are incorporating Leadership in

Energy and Environment Design® (LEED) Silver standards and specifications.

7.1 Property Managers will review projects for their respective Teams using the LEED Silver Design Specifications check list to ensure LEED Silver

Design Specifications are being used.

Property Manager or designee will also perform a cost benefit analysis for projects greater than $5,000.

Chemical Storage & Disposal

The purpose of this procedure is to assess chemical containment, disposal, and spill prevention. Once identified, this information can be communicated to employees working with chemicals to ensure a safe, healthy and environmentally conscience working environment

7.1 Written Hazard Communication Program - all contract employers shall develop, implement, and maintain at each workplace, a written hazard communication program which at least describes how the criteria for labels and other forms of warning, material safety data sheets, and employee information and training will be met. The following must be contained in the written program:

o Name of GSA activity o Address of GSA activity o Inventory of hazardous materials o Normal storage location of hazardous materials o Copy of the Material Safety Data Sheets (MSDS) for each hazardous material o Training criteria for contract employees who use, store, or otherwise handle hazardous materials o A statement requiring each container of hazardous material shall be labeled or marked with the following information Identity of the hazardous material Appropriate hazard warning Name and address of the manufacturer, or other responsible party o Signature of responsible Contract supervisor o Signature of responsible GSA official (e.g. property manager, COR, buildings management tech, etc.)

7.2.6 To furnish the appropriate DFC team property manager a copy of the hazardous materials inventory, at least annually and more often if current supplies are exhausted or deleted from the inventory, or new materials are added.

7.3 The Team Property Manager is responsible:

7.3.1 To ensure copies of the written hazard communication program contains minimum requirements which meet the intent of the program at each activity where hazardous materials are present

7.3.2 To ensure contract employees have required training to handle hazardous materials

7.3.3 To maintain a file of hazardous materials inventories. The MSDS is not required to be filed in the property manager’s office.

7.3.4 To ensure that no associate is exposed to any hazardous material until after completing the required training or verification of contract employees required training

7.3.5 To ensure the criteria established in the written hazard communication program are enforced throughout the life cycle of the hazardous material

7.4 All storage containers that contain any chemical product must be properly labeled. Exception: any container that will be used for that day or shift only does not need to be labeled.

7.5 Employees who are required to handle chemicals must have the appropriate protective gear. Ensure that goggles and or face shields, gloves, spill aprons, etc. are provided and that the employee is trained in the proper use and care of the protective equipment.

7.6 Teams will ensure that all liquid chemicals in storage containers used for;

cleaning, maintenance, pest control, and snow removal will have secondary containment.

7.7 Teams will ensure that smaller containers are stored in appropriate storage cabinets. The chemicals will be stored in such a way that if there is a spill, the different chemicals do not mix and cause either fire, explosion, or an eruption of toxic gas. The types of cabinets used will meet the requirements of the

National Fire Code.

7.8 Employees will use the appropriate PPE when transferring a chemical from a large container into a smaller container.

7.9 Any spills will be cleaned up using an appropriate method and disposed of in approved containers. All spills shall be cleaned up immediately and reported to their supervisor. [the spill containment procedures are typically developed on the type of chemical product that is spilled. This procedure must be outlined in the hazard communication program submitted to the COR from the contractor who will be utilizing chemicals in federal facilities.]

7.10 Any chemicals that no longer have a use in the facility or in the work process and can not be transferred, sold or recycled are considered waste and may be hazardous waste. Waste chemicals are to be transferred to a designated area for storage until disposal. Contact the DFC Environmental Programs Group for proper transfer and disposal instructions.

7.11 The Quality Assurance Inspector and the appropriate COR’s will report any violations to the Team Property Manager who will ensure that the situation is corrected.

Chiller Emissions Program

The GSA Chiller Emissions Program is designed to help ensure chillers are not leaking refrigerant; therefore reducing air pollution. The program will ensure compliance with

Federal, State, local and GSA requirements.

7.1 Review state-specific chiller registration requirements. Ensure that yearly fees are paid, if necessary.

7.2 Refrigerant Inventory and Usage Logs are to be kept by the COR of the

O&M contract for each building as a permanent record after each test. The

COR. will give an additional copy to the Region 8 Chlorofluorocarbons

(CFC) Manager annually.

7.3 Contractor shall test all chillers once a year to ensure they are operating according to the manufacturers’ specifications.

7.4 Contractor shall record any refrigerant added or lost on the Refrigerant

Inventory and Usage Log.

This procedure describes the steps to be taken from when a material is designated to be disposed. This includes the waste streams generated for remodeling/building demolition that are not recyclable, due to volume, purity, and economic factors. Disposal of excavated soil is included in this procedure.

This procedure is divided up into three major divisions with minor subdivisions:

Remodeling/demolition wastes Debris Painted surfaces with lead, chrome, other heavy metals Asbestos

Excavated Soils

Sampling and Manifesting

It is GSA’s intent to recycle all materials, when it makes economic sense.

All above described wastes leaving the facility are required to be transferred to the landfill or an appropriate facility under a waste manifest. All recycled materials leaving the facility are required to be manifested before transfer off the facility. Construction debris, with no known hazardous component shall be manifested as non-hazardous. For materials which have the potential to be hazardous, a TCLP analysis shall be performed (See Sampling and Manifesting Procedure). If the results exceed criteria, the wastes shall be shipped under a hazardous waste manifest. All manifests for the Region 8 shall be signed by a designated signatory within the EPG. An exception to this requirement is the asbestos manifests.

7.1 Remodeling/demolition wastes

The remodeling/demolition wastes debris is being broken down into three major categories:

General Construction Waste Disposal – Hazardous and Non-Hazardous Paint Abatement

Asbestos Containing Material (ACM) Disposal

The Pre-demolition Inspection report and Asbestos Management procedures will have identified the potential type of waste streams identified in the building to be remodeled / demolished. Based on this information and the contractors' knowledge of the work to be performed, the type and volume of each waste that will be generated should be reviewed. Then, the procedure for debris/waste disposal, or recycling is followed. Most demolition material is not hazardous.

Even though the Pre-demolition Inspection report may not identify that a waste stream would be a hazardous waste, the contractor shall notify the CO/COR and the EPG if hazardous waste is suspected. In this case, the material shall be tested for disposal.

When the contractor is choosing what material they are going to test, they should consider the debris that is generated (e.g., a 4” solid wooden wall painted on both sides). A representative sample of the total waste should be collected (e.g., core of the wall with the two painted surfaces. Though the paint itself may fail the TCLP values and be classified as hazardous waste, the analysis is of the entire wall sample may pass and not be classified as hazardous waste. The sample of the entire wall is more representative of the waste as a whole than the painted surface and is allowed by regulation.)

Another example is paint chips from a metal gutter which may fail TCLP for chrome but a billet of the painted metal gutter may pass. Conversely, a waste that contains a very high concentration of a hazardous material that makes up a very small quantity of the total waste volume may cause the entire waste volume to be classified as hazardous for proper disposal. Hazardous waste has drastic cost impacts on your project, with disposal costs going from $17 dollars a yard to upwards of $300 dollars a yard. The contractor and PM should consider characterizing the waste streams prior to the start of a project.

The Contractor shall segregate materials that are known to be hazardous waste(s) from other construction debris when practical.

General Construction Waste Disposal – Non-hazardous waste

This includes all construction wastes not specifically covered under one of the other described categories. This waste has been tested by TCLP analysis and shown to be non-hazardous, or, based on the contractors knowledge of these materials, is known to be a non-hazardous waste.

The amount and type of general construction waste generated by the demolition activity should be reviewed prior to the initiation of the project. The contractor should review the different types and volume of materials to determine if recycling is an economically viable option. If the cost difference between recycling and disposal is close, the contractor will provide the GSA PM information for determining the disposal option. Based on this determination, materials will either be recycled or sent to a landfill, which is licensed to accept these types of materials. In general, construction debris can be shipped to a solid waste landfill. Some landfills have specially designated monofills for construction debris.

General Construction Waste Disposal – Hazardous waste

This includes all construction wastes, which have been tested using TCLP analysis and shown to be hazardous, or based on the contractors knowledge of these materials is known to be a hazardous waste.

The GSA PM shall contact the EPG for assistance. This material will require special storage, labeling, and disposal requirements. The contractor has 90 days from generation to dispose of the waste at a licensed hazardous waste disposal facility.

Paint Abatement

If the contractor is required to remove paint, and based on the review of the Pre-demolition Inspection report the paint may contain lead, chromium, or other regulated compounds, then the contractor shall test the paint (TCLP) for disposal. If a paint remover is used, the MSDS for the product should be reviewed to see if it contains a hazardous material which may contribute to a hazardous waste designation of the removed paint and remover. Alternative products should be reviewed to find non-hazardous removal products.

A typical example of paint abatement is disposal of lead or chromium containing paint from windows that are not being replaced (e.g., historic preservation projects).

The GSA PM shall contact the EPG for assistance. This material will require special storage, labeling, and disposal requirements. The contractor has 90 days from generation to dispose of the waste at a hazardous waste disposal facility.

Asbestos Containing Material Disposal

Based on the review of the Pre-demolition Inspection report and Asbestos

Management Procedure, and any other sampling information pertaining to asbestos, the asbestos removal contractor shall remove this material in compliance with Colorado Department of Public Health and Environment 5CCR

1001, Regulation 8, Part B.

ACM waste shall be properly bagged/containerized and labeled per the regulations. The ACM shall be manifested with manifests signed by the GSA PM or GSA employee directly responsible for oversight of the work as the representative of the owner. The contractor shall not sign the manifest on behalf of GSA. The wastes shall be sent to a licensed landfill permitted to accept this material. The landfill will send the customer copy to the GSA PM, indicating receipt of the waste. The GSA PM is responsible for assuring that manifests are maintained in the project files. This is critical to prevent fines for illegal disposal of ACM waste. An additional copy of the manifest shall be provided to the EPG

7.2 Excavated Soils

Review soil sampling, excavation, and disposal with the EPG.

7.3 Sampling and Manifesting

The following section describes the general sampling procedure for TCLP sampling and characterization of waste streams along with waste profiling and manifesting requirements.

If the Contractor suspects the material may be hazardous they shall collect a representative sample from the roll-off for analysis or pre-demolition sampling.

Contact the disposal facility for testing requirements. The sample shall be sent / delivered to a laboratory for TCLP analysis. This shall be for the full prescribed suite, unless knowledge exists that only metals are suspected, and then a limited suit of RCRA 8 metals will be run. Additional analytical testing other than TCLP may be required by the landfill, depending on the material. These may include the testing for hazardous characteristics (corrosives, reactivity, explosively) and paint filter test for free liquids.

The analytical results shall be transmitted to GSA, and if determined hazardous, to the identified disposal landfill along with the profile sheet. The Contractor shall fill out the waste profile sheet and present it to the GSA’s CO/COR and have the appropriate EPG personnel sign the profile. The Contractor shall submit the profile to the disposal facility for approval. A charge will occur to review the profile.

The disposal facility shall issue the manifest forms based on the Contractor’s provided profile and analytical information.

The GSA’s personnel from the Environmental Programs Group (EPG) will sign the manifest. When the Contractor brings the manifest for signature, she/he shall also bring a copy of the TCLP results and the waste profile sheet. The manifest will not be signed without this information. Any cost incurred because the information is not provided is the responsibility of the contractor.

The Contractor shall then have the transfer truck driver sign the manifest and give the CO/COR the signed “contractors copy” along with a copy of the TCLP results and submitted profile. The original carbon copy of the manifest will be given to the GSA’s EPG representative. The GSA PM will be responsible for putting copies into the project files. The EPG representative may inspect the waste hauler. Based on this inspection which is guided by DOT regulations, the EPG representative may not release the manifest to the truck driver. Any cost incurred because of GSA's refusal to allow the waste to be picked up is the responsibility of the contractor.

The GSA PM shall contact the EPG for assistance. This material will require special storage, labeling, and disposal requirements. EPG will assist in guiding through the disposal effort.

If the Contractor has ACM, they shall manifest the waste.

The disposal facility shall issue the manifest forms based on the

Contractor’s provided information.

ACM manifests will be signed by the GSA PM or GSA employee directly responsible for oversight of the work as the representative of the owner.

The contractor shall not sign the manifest on behalf of GSA The Contractor shall then have the transfer truck driver sign the manifest and shall give the GSA the signed “contractors copy”.

The landfill will send the customer copy indicating receipt of the waste to the GSA PM who is responsible to assure that it gets into the project files. This is critical to prevent fines for illegally disposing of ACM waste.

Copies of both the contractor's copy and the customer copy of the manifest shall be provided to the EPG.

If the Contractor has no knowledge that the material is non-hazardous then it shall be manifested as non-hazardous building debris. The Contractor shall follow the outlined procedure below.

The disposal facility shall be contacted and manifests requested the manifest forms filled out based on the Contractor’s provided profile

The GSA’s designated personnel from EPG will sign the manifest.

The Contractor shall then have the transfer truck driver sign the manifest and shall give the EPG the signed “contractors copy”.

The original signed manifest by the landfill shall be provided to the EPG.

Greening Building Maintenance- Green Purchasing

1.0 Purpose & Scope

It is a requirement at GSA to use Green Products when practical and possible. It is the Policy and objective of the Federal government to be sustainable.

The purpose of this procedure is to:

Inform and instruct GSA personnel, contractors and potential bidders of GSA’s Green Purchasing Policy.

Create a system requiring green product purchasing wherever possible and when this is not, a written statement requesting a waiver is required.

Identify and track the purchase and usage of green products by GSA and their contractors in Region 8 and at the Denver Federal Center (DFC).

Business activities affected by this procedure are, but limited to:

Construction Operations and Maintenance

Custodial/Janitorial Pest Control

Landscaping Snow Removal

Office Supplies

Sections: 2.0 Activity/Department, 3.0 Exclusions, 4.0 Acronyms, and 5.0 Forms Used, are not included, for all information is found in the Procedure Section.

6.0 Procedure

6.1 GSA Policy requires that all new contracts or renewing contract options use Green products, when practical and possible. Green products are environmentally preferable products, which may include biobased, based on recycled content, energy conserving, waste minimizing or

<Title> pollution preventing. These products will be purchased, unless they are not available within a reasonable period of time, not at reasonable prices or unable to meet reasonable performance standards.

GSA personnel, contractors and perspective bidders will search for Green Products (e.g., Green

Seal, EPA’s Environmentally Preferable Purchasing).

Contractors with existing contracts at GSA are not required to switch to Green Products.

However, proposing Green Products that do not have an impact on existing contracts is considered favorable by GSA.

6.2 The Contractor needs to obtain Material Safety Data Sheets (MSDS) of the chemical products that the contractor intends to use in their job function. This is required for safety concerns in case of a fire and this allows the GSA Environmental Programs Group (EPG) to assess that the chemicals are Green Products.

The Contractor needs to identify which chemicals are considered Green Products. The Contractor needs to group the chemicals in appropriate categories.

Cleaners Paper and Paper Products

Construction Products Park and Recreation Products

Floor Care Products Transportation (Vehicular) Products
